The government's first formal response, in nothing less than a press conference, to defend the PM's Chief Economic Advisor Arvind Subramanian and in an aside, RBI governor Raghuram Rajan.

"Arvind Subramanian's advice to government has been invaluable, don't agree with Subramanian Swamy's remarks on the chief economic advisor or Rajan," Finance minister Arun Jaitley said. "His (Arvind Subramanian's) advice to the govt from time-to-time has been of great value. Party has said it doesn't share Dr Swamy's view on Arvind Subramanian," Jaitley said. 

He also said that in the context of the discipline of Indian politicians, how far can you attack people holding office whose discipline does not permit them to respond. "To what extent should we take this?" Jaitley said alluding to Swamy's attacks on both Dr Rajan and Arvind Subramanian. 

Jaitley also denied suggestions that the government and the BJP did not defend RBI Governor Raghuram Rajan in the face of Swamy's attacks, but did not elaborate.

On cue, BJP president Amit Shah piped in saying, the BJP disagreed with Swamy's remarks on the chief economic advisor.

After waging war on Chief Economic Advisor Arvind Subramanian, Swamy on Wednesday said that he has a list of 27 people with him, who are working within the government and need to be 'fixed'.

Staying true to his promise of training guns on bureaucrats 'loyal' to the Congress, Swamy said that he Subramanian to be sacked, as he had badmouthed India in the international arena and had also encouraged the grand old party to become rigid on their GST Bill clauses.

Speaking to ANI after he tweeted against Arvind, Swamy reiterated his salvo he had used against RBI Chief Raghuram Rajan, saying that the CEA was a 'green card holder' and was probably not an Indian citizen.

"He used to work in America and he is also a green card holder type. I don't even know if he is a citizen or not but I'm sure he has a green card. There was this American Congress Committee for pharmaceutical purposes and they held a hearing to figure out India's opinion on the matter. There he said in a statement that India was not working according to America in this matter and for that, they should be taught a lesson in WTO. How can we can such a person an advisor here?," Swamy said.

Continuing his assault, he added that when Arvind was appointed by the Indian government, he gave a note to the Finance Ministry asserting that the clauses given by the Congress in the GST Bill were absolutely justified.

"I think that such people who can fail our government should be tossed out. Now, it's been two years and I think it's about time. I have a list of 27 people in the government and I will slowly, one by one, fix them soon," he added. Earlier in the day, Swamy had launched a scathing attack on Arvind in a series of tweets.

"Who said to US Cong on 13/3/13 the US should act against India to defend US Pharmaceuticals interests? Arvind Subramanian MoF !! Sack him!!! Guess who encouraged Congi to become rigid on GST clauses ? Jaitely's economic adviser Arvind Subramanian of Washington DC," he tweeted. This development comes days after Swamy announced that his next 'project' is to expose a group of bureaucrats loyal to Congress Chief Sonia Gandhi.
